VIOLIN-BOW.

To all whom it may concern:

Be it known that I, FRANK DELLA TORRE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a new and useful Violin-Bow, of which the following is a specification.

My invention relates to improvements in violin bows; and the objects of my improvement are, first, to construct a fibrous violin bow of great strength; second, to construct a fibrous violin bow of substantially uniform fibrous strength per unit of area of the varying cross section areas of the bow; third,the introduction between the fibers of the wood of cement or other like substances whereby the component parts of the bow may be bent and shaped to the desired form before being permanently secured together, which is usually done as follows :-After the component parts are reduced to the desired shape and smeared with glue, they are then put to gether and the whole bent to the required shape before the glue becomes set; fourth, the construction of a bow of governable elasticity; fifth, the construction of a bow of minimum weight with a maximum strength; sixth, the construction of a bow of maximum rigidity with a minimum weight; and seventh, under certain conditions, the construction of a bow which when in use has a maximum weight on the strings of the instrument, but at the same time having the momentum of said bow reduced to a minimum. I attain these objects by the mechanism illustrated in the accompanying drawings, in.which Figures 1, 2, and 3 are views in elevation of my improved bow, showing modified forms of construction; Fig. 4 is a vertical longitudinal section of the bow constructed as shown in Fig. -1 as to the number of parts and the method of construction with the additional feature of a hollow core throughoutthe greater part of its length; Fig. 5 is a cross section of a bow constructed as shown in Fig. 1; Fig. 6 is a cross section showing a modified form of the same construction; and Fig. 7 is a cross section of a bow constructed as shown in Fig. 4 and Fig. 8 is -a cross section of a bow constructed of two longitudinal strips of wood secured together so that the grain of the wood of one strip is at right angles to that in the other strip.

Similar numerals refer to similar parts throughout the several views.

is the stick. is the head. is the nut. is the screw. is the hair.

6 are the strips of which the bow is constructed.

'7 is the hollow core.

8 is a movable weight in hollow core 7.

9 is a plug in hollow core 7.

10 and 11 are splices for ends 12 and 13 and middle section 14.

In Fig. 1 the strips or sections of material of which the stick is constructed are secured together with their gluing surfaces parallel to the aXis of the stick.

Fig. 2 shows a modification of Fig. 1, in which the gluing surfaces are secured together spirally.

Fig. 3 shows a combination of my improved bow with the ordinary bow by means of splicing as shown at 10 and 11.

The material used in my improved bow is substantially the same as that now in use, such as fernambuc wood, bamboo etc., although, in some cases, a combination of materials may be desirable.

The number of strips or sections may vary in different bows, as may also the size and shape of the several strips or sections.

Figs. 1 and 7 show a hollow stick which may be partially filled with a movable weight such as mercury or quicksilver which will remain substantially stationary as the bow is moved back and forth, especially at times when a quick back and forth movement is required, thus reducing the momentum in such movement to a minimum; or said weight may be confined to any part of the stick by means of one or more plugs in barrel 7.

That I claim as my invention, and desire to secure by Letters Patent, is

1. A violin bow consisting of, a stick, hair, means for securing said hair to said stick, and a relatively moving weight attached to said bow.

2. A violin bow consisting of, a stick, hair, means for attaching said hair to said stick, an aperture in said stick, and a movable weight in said aperture.

3. A violin bow stick consisting of separate longitudinal parts secured together along a plurality of planes which intersect within said stick, a head secured to said stick, a nut secured to said stick, and hair UIH CJ LOH between and secured to said head and said nut.

4. A violin stick curved and tapered consisting of, a plurality of separate longitudinal parts secured together along a plurality of planes which intersect Within said stick, a head secured to said stick, a nut secured to said stick, and hair between and secured to said head and said nut.

5. A Violin stick consisting of separate and secured to said head and said nut.
